Device used to close small hole in heart may protect against recurrent stroke
A device used to close a small hole in the heart may benefit certain stroke patients by providing an extra layer of protection for those facing years of ongoing stroke risk, according to the results of a large clinical trial led by UCLA researchers.“It is a major new treatment option for some people,” said Dr. Jeffrey Saver, director of theUCLA Comprehensive Stroke Center and lead author of the study. However, he added, “Using the device is going to have to be a considered clinical decision between the doctor and the patient about who’s the right person to get it.”Thefindings appear in the Sept. 14 New England Jo...

Blood Cell-Bound C4d as a Marker of Complement Activation in Patients With the Antiphospholipid Syndrome
In conclusion the detection of complement activation products on circulating erythrocytes and platelets using a highly sensitive and specific assay further supports the view that APS is a complement-mediated disorder. Increased EC4d and PC4d percentages are associated with the active inflammatory disease in SLE. It is difficult to translate this finding to APS which is a non-acute inflammatory disorder. We failed to find an association with both the classification and non-classification criteria, including thrombocytopenia. However, we believe that this sensitive tool to evaluate complement activation may offer more inform...

Lessons Learned from Managing Antithrombotic Therapy in Children Supported with Pediatric Ventricular Assist Devices
Stroke, thromboembolism, and bleeding are the most recognized complications associated with pediatric ventricular assist devices (VADs) and the leading cause of death and disability on VAD support. Recently, newer antithrombotic strategies like bivalirudin have emerged that appear to be associated with a reduction in the neurologic event rates, especially for smaller pediatric-specific VADs like the Berlin Heart and PediMag/CentriMag systems where the risk of stroke is the highest. While contemporary antithrombotic therapies have likely contributed to lowering adverse event rates, we speculate that clotting and bleeding ad...
